I-30-TW Interior timber-framed 30 minute FRR windows, single glazed

The I-30-SW is NZFD’s interior 30 minute fire-rated window unit in a timber frame. It is available in a wide range of pane combinations and is made to order. Each pane is generally manufactured separately for ease of transport and on-site handling (weight and size), then assembled on site. Depending on size, pre-built multiple pane units are available ex-factory. Your choice of glass affects available pane sizing and fire rating options.
